2014 — Treatment of Produced Water Using Dissolved Air Flotation (DAF) Technique and Ionic LiquidsAbstract
As population grows, more water and oil resources are needed to make more products. In addition, more contaminants are also created due to daily uses. Consequently, environment protection will be a necessary duty for everyone. As produced water is a by-product from the oil production process, and constitutes a large portion of the extracted liquid from the oil well, treatment of the produced water is necessary before discharging. Treatment of produced water is a benefit for many reasons such as extracting more oil from the produced water, using the treated water for irrigation, and finally for protecting the environment. In … Read more

2014 — Hydrogen Production by the Cataylitic Auto-Thermal Reforming of Synthetic Crude Glycerol in a Packed Bed Tubular ReactorAbstract
The target of this work was to develop an efficient autothermal reforming (ATR) process for the production of renewable hydrogen from synthetic crude glycerol (CG). Hence, the work was divided into three phases: (1) development of a high performance catalyst, (2) optimization of process variables, and (3) investigating the kinetics of the involved reactions. A portfolio of ternary oxide catalysts with a nominal composition of 5Ni/CeZrM (where M= Ca, Gd, Mg) was prepared, characterized and tested in the process. A series of experiments was conducted in a Packed Bed Tubular Reactor (PBTR) using a factorial design technique to investigate the … Read more

2014 — Mechanisms of Oil Recovery During Cyclic CO2 Injection process: Impact of Fluid Interactions, operating parameters, and Porous MediumAbstract
Carbon dioxide (CO2) injection processes are among the most promising enhanced oil recovery techniques based on their great potential to improve oil production while utilizing geological storage of carbon dioxide to reduce greenhouse gas emissions. Among various CO2 injection modes, cyclic CO2 injection (CO2 huff-and-puff) scenarios have seen significant increase in interest for the purpose of enhanced oil recovery (EOR) in both non-fractured and fractured reservoirs. Several operating parameters, including operating pressure, solvent (CO2) injection time, soaking period, water saturation, etc., affect the performance of this process. However, the number of studies that consider these parameters is relatively limited. In … Read more

2014 — Clarifying the Nature of Pain-Related Anxiety: Implications for Assessment and Treatment of Chronic Musculoskeletal PainAbstract
Pain-related anxiety and anxiety sensitivity (AS) are important constructs in fearanxiety- avoidance models of chronic pain (Asmundson, P. J. Norton, & Vlaeyen, 2004). Pain-related anxiety (McCracken & Gross, 1998) includes dimensions of cognitive anxiety (e.g., concentration difficulties as result of pain), behavioural avoidance, fearful thinking about pain, and physiological reactivity to pain (e.g., autonomic arousal, nausea). AS (Reiss, Peterson, Gursky, & McNally, 1986) is the trait tendency to fear the physiological sensations of anxiety due to the belief such sensations signal imminent harm. Evidence suggests an association between AS and pain-related anxiety (e.g., Muris, Schmidt, Merckelbach, & Schouten, 2001; P. … Read more

2014 — Investigating the Prevalence and Persistence of Different Escherichia Coli Genotypes in an Agriculturally Influenced Aquatic EcosystemAbstract
In several regions of Canada, including Saskatchewan, surface water such as streams and rivers are utilized as primary sources of irrigation water for fresh produce. Surface water can be exposed to faecal pollution from various sources such as storm water runoff, failing septic systems, and agricultural waste runoff. The use of faecally contaminated water in irrigating fresh produce may lead to food-borne outbreaks when enteric pathogens are present in the faeces. The ability to predict the presence of faecalderived pathogens is therefore important in assessing the human health risks associated with the use of open source irrigation water. Escherichia coli … Read more

2014 — LA PASSIVITÉ DE LA DYNAMIQUE MOTIVATIONNELLE DANS LA FORMATION DES VOCABULAIRES GASTRONOMIQUES FRANÇAISAbstract
The study of role of motivation in the formation of new vocabulary and terminological units, taking into account the semantic relationship that exists between linguistic signs and their referents, is not new. This is an area that has generated lots of discussions and debates over the years. There have been various philosophical, sociological, linguistic and terminological arguments that motivation is indispensable in the course of word formation in French and that it exercises enormous influence on the referents of new words. However, there are other arguments that consider motivation as a non - factor in the formation of new words … Read more

2014 — Prediction of Retail Prices Using Local CompetitorsAbstract
One of many applications of data mining is the prediction of retail prices. Often the price of a product at a store depends on the price of the same product at other stores. Our focus is to predict two types of prices, i.e., the start of the day price of the product at each store in a city and the real time (current) price of the product at each store in a city. We focus on predicting the product prices by identifying competitors of a store, for various notions of competitors. We also consider relevant information that could help us … Read more

2014 — Integrating Ontology-Based Information Extraction Systems and Spatial Modeling for Land Use Analysis and SimulationAbstract
Information Extraction (IE) is defined as the automatic identification and extraction of a predefined set of concepts, relevant to a specific domain of knowledge, ignoring irrelevant information. IE converts unstructured text into structured data and extracts the required information. IE is to some extent domain-specific. In IE, the information to be extracted must be specified a priori. In the context of IE, the ontology is used to structure and represent the domain knowledge. The IE system extracts information with respect to the domain ontology and then populates the ontology with the extracted information. This process is referred to as Ontology-Based … Read more

2014 — Transdiagnostic Internet-Delivered Cognitive-Behaviour Therapy for Recent Cancer Survivors: A Feasibility Trial and Examination of Clinician PerspectivesAbstract
Increased attention has been drawn to the challenges faced by cancer survivors following treatment completion. Although most survivors adjust well to these challenges over time, a subset of individuals experience clinical levels of anxiety and depression. Cognitive-behaviour therapy (CBT) has been shown as effective in reducing anxiety and depression among individuals who have received a cancer diagnosis. Despite the availability of this treatment, a large proportion of cancer patients and survivors do not seek treatment for emotional distress due to reasons such as geographical distance from providers, and the stigma of seeking help for mental health problems. Internet-based CBT (ICBT) … Read more

2014 — The Influence of Hardiness Levels on the Rate of Return to Work For Those who Have Sustained a Back InjuryAbstract
Existentialists suggest that our responsibility is to discover our own meaning in life which can be recognized through creative works, experiences and relationships, and attitudinal acknowledgement and/or choice of one’s current circumstances (Frankl, 2006). It is through the will to meaning, the primary motivational drive noted by Frankl, that humans are able to transcend and live a fulfilled life despite perceptions of unavoidable sufferings. Therefore, existential courage/hardiness helps one to engage in coping with problems rather than denying or avoiding them. Furthermore, it also relies on socially supportive interactions with others and the capacity to learn from this perpetual process … Read more

2014 — Who was This Woman: A Narrative of the Lived Experiences of the Daughter of a Pioneer Who Became a TeacherAbstract
This thesis is a narrative inquiry of my mother’s lived experiences before she became a teacher in a one-room school house in 1930s Saskatchewan. There have been numerous memoirs written by teachers of rural schools. After reading a wide assortment of these memoirs I noticed that they were mostly of classroom experiences. There is a dearth of information about the lived experiences of these teachers, many of whom were women, prior to their actual classroom teaching. With my mother as a co-inquirer, we narratively explored her lived experiences in her journey into the story of becoming a teacher. Narrative research … Read more

2014 — Impairments, Health-Related Physical Fitness, and Leisure Time: Physical Activity Following Spinal Cord InjuryAbstract
A spinal cord injury (SCI) can lead to impairments that impact fitness, health and quality of life. Although advances in medical technology have increased survival rates, individuals with SCI continue to experience various health problems that may be associated with a decrease in overall fitness. Physical activity has the potential to improve health-related physical fitness levels. According to the most recent physical activity guidelines, individuals with SCI should participate in 20 minutes of moderate-to-vigorous intensity leisure time physical activity (LTPA) two times per week (Ginis et al., 2011). These physical activity guidelines also recommend 3 sets of 8 to 12 … Read more

2014 — Pressure Pulsing Potential During Waterflooding and CO2 Flooding of Heavy Oil ReservoirsAbstract
The world is facing a challenge of limited sources with respect to hydrocarbons. Society has become so dependent on oil and natural gas that no one can imagine life without the resources. Oil and gas deposits are limited and the main portion of conventional reservoirs is at a late stage of development, hence, the market price for oil and gas is continuously increasing. The need for development of new technology for oil recovery from unconventional reservoirs has become a priority. Canada owns more than 40% of the world’s heavy oil. This means traditional methods of oil displacement, namely waterflooding or … Read more

2014 — Investigating Decision Making With Game-Theoretic Rough SetsAbstract
Rough set theory and game theory provide two approaches for analyzing and assisting decision making. Rough set theory provides the ability to make decisions with incomplete and insuffcient information. On the other hand, game theory concerns with decision making where an outcome depends on interaction between two or more decision making criteria. A fundamental challenge in the application of rough sets is how to reduce the uncertain boundary region by configuring the parameters or thresholds defining the region bounds. The game-theoretic rough set (GTRS) model provides a game-theoretic perspective for setting and computing these thresholds. The conventional rough set model … Read more

2014 — “Always in the process of Becoming”: Inquiring Narratively Into Providing Purposeful Support Towards Critical Social Justice EducationAbstract
Even as teacher education programs raise issues of social justice with pre-service teachers, the opportunities for them to practice their skills happen within the existing school structure— a structure that resists change. Many cooperating teachers who mentor pre-service teachers during their internship hold common-sense and taken-for-granted assumptions about what it means to be a “good” teacher that can interfere with the practice of critical social justice pedagogy. This narrative inquiry begins with an autobiographical exploration of my origins as a social justice educator and then examines the relationship between me, a cooperating teacher, and an intern as I strive to … Read more

2014 — Passing Trauma Through Generations: Child Sexual Abuse as Perceived by CounsellorsAbstract
The purpose of this research was to understand how private counsellors, school counsellors and Indigenous holistic counsellors perceived the notion of Child Sexual Abuse (CSA) as an intergenerational phenomenon and to draw on their beliefs to gain understanding about the various causes, process, and effects of CSA. Child Sexual Abuse was examined here as an intergenerational occurrence with causation in families’ previous exposure to the phenomenon. This subject was investigated using qualitative research methods, namely Grounded Theory. The phenomenon of Child Sexual Abuse recurring in subsequent generations was explored through in depth interviews. Three self-identified Indigenous holistic counsellors (two male, … Read more

2014 — Single View Coplanar Photogrammetry and Uncertainty Analysis for Traffic Accident ReconstructionAbstract
Photogrammetry is defined as the science of measuring distances and objects by using photographs. Rapid advances in computer technology and digital photography in recent years have resulted in growing applications of digital photogrammetry. Although various aspects of photogrammetry have been investigated; the question of uncertainties in measurement, which is important for forensic applications, such as traffic accident reconstruction, has not been widely explored. This study attempted to develop an applicable comprehensive mathematical model to perform coplanar photogrammetry and provide a measure of uncertainty for its measurements. Photogrammetry requires information about the interior and exterior orientation of the camera. Process maximum … Read more

2014 — Media (Mis)Representations and the Muslim Body: A Lived CurriculumAbstract
My research explores the ways in which dominant media (re)presents, embodies, and constructs Omar Khadr in contradistinction to “real” Canadians, reflects upon the potential consequences of such representations for both “strangers” and “exalted subjects,” and contemplates as well ways to disrupt both these dominant and oppressive narratives. I also provide a framework for Khadr’s case as it relates to the biopolitical – that is the management of bodies by regimes of truth. To do this I analyze the larger context under which Omar Khadr’s case has unraveled by considering the ways that different techniques of management (re)produce bodies in complex … Read more

2014 — Root Dynamics, Management Effects and Carbon Sequestration on Invaded and Native Semi-Arid GrasslandsAbstract
Root dynamics are a major component of terrestrial ecosystem processes but they have not been broadly studied, due to the difficulty of quantifying root production and mortality. The use of minirhizotrons facilitates belowground research, but sample intervals are controversial since long intervals miss roots that grow and die between the samples. Also, root responses to grassland management such as mowing are less well-known than shoot responses, even though as much as 83% of productivity in semiarid grasslands occurs belowground. Finally, the belowground dynamics of invasive species that change the vegetation of an area can be expected to alter the local … Read more

2014 — The Prevalence of Bacteria-Sediment Associations and Their Effect on Sediment Settling Velocities in Aquatic Environments of Agricultural Saskatchewan and Alpine British ColumbiaAbstract
Bacteria-sediment associations (BSA) are the natural interactions between bacteria and sediment particles that influence both bacterial survival rates and properties of sediment particles. A newly developed method for quantifying BSA was applied to an agricultural watershed in southeastern Saskatchewan and an alpine watershed in the southern Coast Mountains of British Columbia. Both watersheds exhibited spatial and temporal trends of BSA. Impacts corresponding to land use and anthropogenic activity are also present. Development of a novel method for determining BSA allowed for samples taken from remote areas to be assessed. Membranes with 8 μm pore diameter separated planktonic organisms from sediment-associated … Read more

2014 — Sea FoamAbstract
Sea Foam is a collection of fairy tale poems. These poems draw from the themes, characters, and types of various fairy tales, ranging from the well-known tales of the Grimm Brothers and Charles Perrault to lesser-known tales from older or more obscure sources. The first section features the mermaid as a symbol of transformation. The second section focuses on fairy tales about the fear of change and the dangers of stasis. Finally, the third section tells the story of a woman who sees her life as a series of fairy tales. Sea Foam focuses on the theme of transformation in … Read more

2014 — Psychology’s Philosophical Foundations: In Search of a Unifying TheoryAbstract
I am concerned with fragmentation in psychology among its theories and research projects. There is in particular a clear debate between those who propose a scientific conception of psychology versus those who propose a broader, more expansive conception of its subject matter and method. The proponents of these two opposed conceptions of psychology agree that psychology is in need of an epistemology. I argue, instead, that psychology first needs to identify its metaphysics. That metaphysics will be its subject matter, as well as what is required for the study of any subject. I propose that Psychology’s metaphysics is the person, … Read more

2014 — Executive Function, Social Emotional Learning, and Social Competence in Autism Spectrum DisorderAbstract
The main objective of this study was to investigate the concurrent role of multiple antecedents of social competence in a group of children with Autism Spectrum Disorder (ASD). Existing models of social competence were adapted to include three domains of executive function (EF: Cognitive, Behavioural, and Emotional Regulation), and two domains of Social Emotional Learning (SEL: Nonverbal Awareness, Social Understanding). The EF domains were related to sustained attention, working memory, planning, behavioural inhibition, and affective decision making; SEL domains included social comprehension, and identification and interpretation of social cues. Social competence was defined in terms of social skills and adaptive … Read more

2014 — Parental Differential Treatment for Adult Children: Interactions, Implications and InterventionsAbstract
Parental Differential Treatment (PDT) is the conscious or unconscious action of providing one sibling more favorable treatment over another. PDT has consequences for children‟s lives. Several consequences have been identified for children who experience PDT; however there is a dearth of literature exploring the effect of PDT on adult life. This qualitative, phenomenological study is an effort to better understand the lived experiences of adult children with PDT, and its effect on their current adult life. Four people, between the ages of 25-55 who have experienced, or continue to experience PDT participated in this study. The “Modification of the Stevick-Colaizzi-Keen” … Read more

2014 — Depositional and Dewatering Behaviour of Uranium Mill TailingsAbstract
The Key Lake operation in Saskatchewan, Canada, is the largest uranium mill in the world. This mill process generates tailings that are deposited into an onsite storage area called the Deilmann Tailings Management Facility (DTMF). An effective tailings management scheme requires a clear understanding of slurry behaviour throughout the life-cycle, starting from production thorough the deposition to dewatering in the storage facility. The main objective of this research was to investigate the depositional and dewatering behaviour of uranium mill tailings (4%, 5%, and 6% mill tailings) from the Key Lake operation under laboratory and field conditions. All of the samples … Read more

2014 — The Impact of Governance and Remuneration Reform on Primary Mental Health Care: A Comparative Analysis of Three Canadian ProvincesAbstract
Introduction: The quality of general practitioner-delivered primary mental health care (PMHC) is a concern for Canadian policy-makers. To improve quality, policy reforms must target the length of consultations, interdisciplinary collaboration, and system coordination. PMHC governance and physician remuneration are structural barriers that impede quality improvement efforts. Purpose: The purpose of the research is to determine which PMHC governance and mode of physician remuneration policy reforms can most effectively facilitate greater system coordination, interdisciplinary coordination, and longer, more involved consultations in Canadian PMHC. Methods: A comparative case study of three Canadian provinces, specifically British Columbia, Manitoba, and Saskatchewan, was completed. These … Read more

2014 — Relational Verbs: Paradigm and Practice in a Manitoba dialect of Swampy CreeAbstract
This thesis studies the verbal inflection in Cree called the relational form, with a focus on Western Cree dialects, primarily Swampy Cree as spoken in Kinosao Sipi (Norway House), Manitoba. I will overview previous literature on the topic, from early grammarians Horden (1881), Howse (1844) and Lacombe (1874) to more modern accounts from Ellis (1971, 2000, 2004), Junker (2003) and Wolfart (1973). As well, textual evidence will be discussed for the relational paradigm in Cree dialects from text collections and publications by Ahenakew (1987a), Bloomfield (1930, 1934), Ellis (1995), Kâ-Nîpitêhtêw (1998), Minde (1997) and Wolfart & Ahenakew (1992, 2000). Following … Read more

2014 — Weyl’s Construction of the Irreducible Regular Representations of the Complex Classical GroupsAbstract
The main objective of this work is to construct all the regular representations of the complex classical groups. Since each of these groups is reductive, in the sense that every regular module is a direct sum of irreducible regular modules, it su ces to construct the irreducible ones. We achieve this by using Weyl's method, which provides an explicit and concrete realization of each of the desired modules. Chapters 1 to 3 contain background information. The reader may choose to skip them and consult them only when necessary. Chapters 1 and 3 describe the relationship between the classical groups and … Read more

2014 — Inexact Inventory-Theory-Based Mathematical Programming For Municipal Solid Waste Management Under Multiple UncertaintiesAbstract
With the population growth and the increase of waste generation throughout the world, municipal solid waste (MSW) management has become a critical issue for urban environment. Numerous factors, such as shrinking waste disposal capacities, increasing environmental and health concerns, and varying legislative and political conditions, influence the planning of MSW management in the real world. When planning MSW management, the problems of waste-flow allocation and waste inventory should be addressed by waste managers. Moreover, various uncertainties exist in these problems and may be further intensified due to complex features of the system components. Therefore, in response to these challenges, effective … Read more

2014 — A Rough Set Approach to Face RecognitionAbstract
Rough decision tables were originally proposed by Pawlak. The hierarchies of probabilistic decision tables (the hierarchies), defined in the context of Variable Precision Rough Set Theory (VPRS model), generalized this notion. In recent years, the hierarchies have been successfully applied to many research areas. Compared to other facial representation and recognition techniques, the hierarchies have several unique advantages. As a classifier, the hierarchies can update their structures dynamically and meanwhile maintain prior knowledge when new face images appear. In addition, the most relevant features of facial representation and recognition can be selected heuristically, and the structure of the template images … Read more

2014 — The Development of Context-Specific Biofeedback Training Screens – An Application to Hockey OfficialsAbstract
The benefits and potential of biofeedback training for enhancing athletic performance has received noticeable consideration in both research and practice. While most biofeedback research applied to sport participants has focused primarily on athletes, one group of participants has been neglected in both research and training. This group is known as sports officials. Ice hockey officials are required to possess various physical, cognitive, and psychological skills, suggesting that biofeedback training to enhance their on-ice performance holds strong utility. Since biofeedback research applied to sport offers very little perspective into the needs and requirements of biofeedback protocols applied to officials of sport, … Read more

2014 — Engagement in Health Education: Just a Fairy Tale?Abstract
Engagement is increasingly used to describe students’ involvement and investment within their learning environments. Student engagement continues to be part of the student achievement conversation in Saskatchewan. The purpose of this study is to examine what constitutes engaged learning for grade 8 health education students and to develop a deeper understanding of how a teacher plans for and supports student engagement in health education. This single case study is guided by two research questions: How do students understand engagement? How can a grade 8 teacher plan for and support student engagement in health education? Drawing on the method of case … Read more

2014 — Using Occupancy Models to Predict Grassland Bird Distributions in Southeastern AlbertaAbstract
Widespread population declines of grassland birds have stimulated a variety of conservation plans, many of which promote a landscape approach to conservation. Identifying needs for survival and reproduction, and prioritizing key habitat requirements that influence where species occur on the landscape is an essential first step to guiding long term management efforts. I used single-species, single-season occupancy models to (1) identify landscape factors influencing the distribution of grassland bird species, (2) generate predictions of species distributions in southeastern Alberta, and (3) evaluate the predictive performance of each species model with two sources of evaluation data. In 2012, I conducted three … Read more

2014 — Reflections on Career Development: A Phenomenological Study of Women Who Coach Canadian High Performance Male Track and Field AthletesAbstract
Canadian female coaches are typically young, single and without a family, leave within the first five years of coaching, often hold part-time positions and are unlikely to coach male athletes (Kerr, 2010; Reade, Rogers & Norman, 2009). Further it has been suggested that the Canadian sport system does not adequately support women’s entry into the coaching profession (Kerr & Ali, 2012; Kidd, 2013). Several studies have explored the challenges female coaches face in establishing a career and working in sport (Kamphoff, 2010; Kerr and Marshall, 2007; Kilty, 2006; Norman, 2010a, 2010b; Staurowsky, 1990; Theberge, 1993; West, Green, Brackenridge & Woodward, … Read more

2014 — Targeted knockout of PpASCL, an anther-specific chalcone synthase-like gene, supports role in sporopollenin biosynthesis in the moss Physcomitrella patens.Abstract
The anther-specific chalcone synthase-like (ASCL) gene of Physcomitrella patens, PpASCL, has been implicated in the biosynthesis of sporopollenin, the main constituent of exine and perine, the two outermost layers of the moss spore cell wall. Targeted knockouts of PpASCL were produced and the resulting mutants characterized. Knockout plants developed normally until late in sporophytic development, when the spores produced were aberrant and non-viable. The development of the spore cell wall appeared to be arrested early in microspore development, resulting in small, collapsed spores with irregular surface morphology. These results suggest that PpASCL plays an important role in the proper formation … Read more

2014 — Linguistic Analysis of Communication in a Therapist- Assisted Internet-Based Cognitive Behaviour Therapy Program for Individuals with Generalized Anxiety DisorderAbstract
Background: Therapist-assisted Internet-based Cognitive Behaviour Therapy (TAICBT) is an empirically supported method of treating generalized anxiety disorder (GAD). In addition to the cognitive and behavioural elements found within face-to-face Cognitive Behaviour Therapy (CBT), TAICBT includes elements of expressive writing, through email communication with a therapist. Expressive writing has been associated with positive outcomes; furthermore, certain linguistic dimensions in expressive writing have been associated with psychological and physical health benefits, such as less frequent use of negative emotion words, and greater use of positive emotion words. No research to date has analyzed linguistic dimensions in client communication over the course of … Read more

2014 — An Examination of Attentional Bias for Threat in a Motor Vehicle Accident Survivors with Posttraumatic Stress DisorderAbstract
Theoretical models of anxiety suggest that cognitive vulnerabilities are involved in the development and maintenance of posttraumatic stress disorder (PTSD; Elwood, Hahn, Olatunji, & Williams, 2009). Attentional bias for threat has been identified as a cognitive vulnerability which may facilitate the development and maintenance of PTSD (Bomyea, Risbrough, & Lang, 2012). Several cognitive tasks have previously been used to assess attentional bias for threat in anxiety pathologies (i.e., emotional Stroop task, visual search task, dot probe task). The proposed investigation was designed to assess the directionality (i.e., facilitated attention, difficulty in disengagement, avoidance) and time-course of attentional bias for threat … Read more

2014 — Life History, Nurse Empathy, and Aggressive Behaviours in Individuals with DementiaAbstract
Dementia is common among long term care (LTC) residents and has many implications for their quality of life. Individuals with dementia often present with behavioural disturbances such as aggression (e.g., destructive actions toward persons, objects, or the self) that negatively affect their quality of life and may result from unmet needs (Whall et al., 2008). Egan et al. (2007), using a very small patient sample (N = 4; no control group), successfully piloted an intervention intended to influence professional caregivers’ behaviour toward residents, and thus decrease aggressive behaviours by presenting staff members with life histories of the residents. The goal … Read more

2014 — The Origin of Adakites in the Garibaldi Volcanic Complex, Southwestern British Columbia, CanadaAbstract
The Garibaldi Volcanic Complex (GVC) is located in southwestern British Columbia, Canada. It comprises two volcanic fields: the Garibaldi Lake Volcanic Field (GLVF) in the north and the Mount Garibaldi Volcanic Field (MGVF) in the south. Petrographical and geochemical studies on volcanic rocks collected from the GVC have determined that they exhibit adakitic characteristics; these intermediate rocks range from basaltic andesite to dacite represented mainly by lava flows, domes and minor pyroclastic material. All the lavas exhibit evidence of magma mixing, which include sieve textured crystals, dehydration reaction textures, differently sized phenocryst populations, xenocrysts and xenoliths. The geochemistry of the … Read more

2014 — “Just a Pepper in a Bunch of Salt”: Aboriginal Students’ Stories of SchoolAbstract
Mirroring national trends, the Saskatchewan education system is failing its Aboriginal students. The situation is urgent, evidenced by low rates of Aboriginal students transitioning through the grades, their lower results on provincial assessments, and the significant gap between Aboriginal students and their non-Aboriginal counterparts graduating from high school. In light of these issues, this research explores high-school aged Aboriginal students’ stories of school and in particular their stories of place, curriculum, teachers and administrators. The research recognizes schools as white spaces where dominant identities are affirmed through place, spaces, curriculum, and pedagogy. Data was collected through four semi-structured interviews with … Read more

2014 — Lineup Composition Effects on Eyewitness IdentificationAbstract
Whenever lineups are prepared for eyewitness identification, the investigator constructing the lineup must decide how to choose lineup members to appear in the lineup with the person under investigation. Accordingly, three research projects were conducted to inform lineup construction practices. The first project is a meta-analysis of lineup similarity effects. Results of the meta-analysis suggest that biased lineups yield the highest rate of suspect identifications, regardless of whether that person is guilty or innocent. When lineups with moderately similar members are compared with lineups containing highly similar members, increasing similarity reduces innocent suspect identifications and has only a small and … Read more

2014 — Evaluation of Contaminant Containment at Regina LandfillAbstract
Landfill and waste containment facilities are routinely constructed on natural or engineered low permeability barriers placed above or within the vadose zone to prevent contaminant migration into the groundwater system. Numerical estimates of design lives for assessment of barrier system performance are generally acceptable under numerous landfill regulations. Predictive models work under the general assumption that constructed systems will retain their structural integrity over the design life of the landfill and act as leak proof systems. Contrary to the above assumption, barrier performance, whether natural or engineered, at countless landfills and waste disposal sites across North America suggests that these … Read more

2014 — Living a Curriculum of Tensions: Experiences of Learning to Teach Physical EducationAbstract
This narrative inquiry explored two pre-service teachers’ experiences of learning to teach Physical Education during a 16-week internship. My interest emerged from my experiences as a student, pre-service teacher, teacher, cooperating teacher, supervising faculty, and teacher educator. I began by inquiring into my own stories of experience. Wonders emerged as I explored literature about learning to teach and juxtaposed a Deweyan conception of experience with other research paradigms such as post-positivism, Marxism, and post-structuralism. While traversing these borderland spaces and inquiring into my own stories of experience, a research puzzle was named: how learning to teach is experienced by pre-service … Read more

2014 — Circles of Support and Accountability (CoSA) in Regina Saskatchewan, 1997-2011: Exploring the Perceptions of Key StakeholdersAbstract
Sex offenders are typically ostracized by both the media and public, rather than seen as individuals in need of support upon their release into the community. There are services such as restorative justice programs that exist which provide support for their successful reintegration. This study sought to understand the personal views of sex offenders and community volunteers concerning the efficacy associated with such restorative initiatives. The study examined a selected group of sex offenders who were deemed high risk at the time of their incarceration and then released, as well as, volunteers and professionals who are actively involved with the … Read more

2014 — The Punjab Problem: A Case Study on the Rise of Sikh Nationalist Identity in India,Abstract
Sikhs are among the many religious groups present in India. They are also one of the many minorities who have suffered since India’s independence in 1947. Since then, issues including the keeping and maintaining of its identity, growing fears of assimilation by Hindu fundamentalists and religious discrimination has surrounded the Sikh minority. The events of 1984 have also presented a new development in the Sikh identity, particularly the emergence of a separate and nationalist Sikh identity. What has caused the feeling of insecurity and the sudden rise of Sikh nationalistic identity within post-independent India? Through the use of evidence, historical … Read more

2014 — Brewing Identity: Fair-Trade Coffee, Image, Style and Consumerism in Late CapitalismAbstract
Since the collapse of the International Coffee Agreement in 1989 the production of coffee has been in crisis.
